2021 Buick LaCrosse eAssist Hybrid Review



2021 Buick LaCrosse eAssist Hybrid - Electrification is maybe the automotive buzzword today, yet General Motors has actually been offering various hybrids for greater than a years. The Buick department released its initial such vehicle back in 2012: the LaCrosse eAssist, a crossbreed variation of its large car that proceeded through the 2016 version year. When the third-generation LaCrosse was launched for 2017, the technology was missing from the order sheet, however Buick reupped on the hybrid for 2018. The four-cylinder eAssist currently is the entry-level powerplant. Unlike lots of eco-themed lorries that telegraph their green-leaning powertrains, nonetheless, the LaCrosse keeps its electrification on the down low.

Take a walk around the LaCrosse and also there are just four badges visible: the Buick tri-shield logo on the grille and also the facility of the trunklid, Buick defined on the left side of the trunklid, as well as LaCrosse on the ideal side. There's absolutely nothing else on the back or on the body sides to indicate that this auto has hybrid innovation under the skin. Not even a funky color selection like bright environment-friendly, chrome yellow, or electrical blue. Our examination vehicle was white with chrome wheels-- classy however traditional.

The very same visual executes to the inside. There's no strange dashboard setup for the sake of being various, no oddly patterned or tinted trim, no oddball shifter. The one point that hints something eco-friendly is taking place is a little electronic leaf on the appropriate side of the scale cluster; it works as the needle on a meter that ranges between ACCEL as well as BRAKE. Seeing such tags may seem silly considering exactly how primary those jobs are in any type of car, but it represents the two locations where the eAssist system comes into play.

This branch of GM's family members of green equipments can be traced back to Saturn-- remember that brand name?-- which released the Vue Eco-friendly Line SUV for the 2007 design year. The Environment-friendly Line presented the belt-alternator-starter (BAS) system. The BAS modern technology has actually been related to lots of GM cars since then, incrementally improving with the years as well as becoming marketed as eAssist. It uses automated stop/start as well as a small amount of electric assist and regenerative stopping to increase fuel economy.

In the LaCrosse, the hybrid system includes a 2.5-liter inline-four gas engine, an electrical motor/generator, and a 24-cell 0.5-kWh lithium-ion battery pack. The electrical motor, which GM calls the Motor Generator Unit (MGU), replaces a traditional generator as well as is belt driven or belt driving, depending on its setting. Regenerative stopping gathers power, the MGU converts it to power, as well as it's kept in the air-cooled battery pack.


When the LaCrosse pulls up, the gas engine shuts down and also the battery powers the remainder of the vehicle's functions, such as the infomercial as well as HVAC systems. It's then utilized to reboot the engine when the brake is released as well as could also supply added torque when the vehicle driver presses the accelerator. Buick claims it gives 9 percent much more torque compared to the previous LaCrosse eAssist, plus the system's general size is smaller sized and has actually been packaged extra successfully.

Even so, the battery strikes trunk room. Although the rear seats fold up down, the rectangle-shaped bump in the trunk floor stretches across the pass-through opening to the automobile's cabin. The loss of cargo space is only one cubic foot (14 versus 15), yet the interruption of the lots flooring makes it more of a hinderance compared to those numbers recommend. Still, it's much less intrusive than the previous LaCrosse eAssist's battery pack.

Just how Light Is Light Electrification?
The 2018 LaCrosse eAssist is EPA-rated at 25 mpg city, 35 highway, and 29 combined, which is only a little boosted from the 2016 design's 24/35/28 rankings. We averaged 27 mpg general and handled a remarkable 38 mpg on our 75-mph freeway fuel-economy examination. The higher-trim LaCrosse models come with a V-6 engine; when we examined a front-wheel-drive V-6 version-- 152 extra pounds much heavier than this front-drive eAssist-- it took care of just 31 mpg on its freeway run as well as returned 24 mpg overall.

The eAssist, which utilizes a six-speed transmission, took 7.8 seconds to speed up from zero to 60 mph, which is neither antarctic nor zesty. Paired with an eight-speed automated, the V-6 in the 2017 LaCrosse (2018 V-6 LaCrosses have a nine-speed automated) revealed impressive thrust and propelled the front-wheel-drive version to 60 in 5.9 secs; an AWD model moved off the line slightly quicker, at 5.8.

So the enter gas economy comes with a substantial price in velocity. Yet a minimum of the crossbreed system is imperceptible in operation. The only indication that the powertrain is aiming to conserve gas is the stop/start function, and that feature is now basic on lots of nonhybrid vehicles.


For the rare people who fondly reminisce about the times when couches on wheels wandered the streets, the LaCrosse is a sentimental blast from the past. At virtually 200 inches long, the LaCrosse is big, as well as it drives like it. The guiding is slow with no indicator of just what's taking place beneath the car, and around transforms it really feels as if the body is perched in addition to a Bosu round. It's not floaty, nonetheless, but rather deliberate and regulated.

The disconnect in between the roadway and the driving experience does create an extremely calm cabin. The powertrain is smooth and silent, road sound is successfully blocked, and bumps are easily dispatched without disturbing the ride.

The interior does not feel as costs as it need to considering our test auto's close to-$45,000 price. The dashboard is clean and also well organized, yet the format drew some issues, as the massive facility console eats space and creates a confined sensation for the motorist as well as front passenger. The area to be in this Buick is the loungelike rear seats. Headroom and also legroom in the rear are generous, the seats are plush, and also the trip is flexible. We would certainly be delighted if our Lyft vehicle driver brought up in among these.

And also with its impressive gas mileage, the LaCrosse eAssist undoubtedly would certainly be a solid option for a part-time taxi. For those that don't such as the sacrifices that usually include a crossbreed, this Buick offers extra mileage in a comfy and understated package.
